ViewPoint3 plug in missing from Photoshop CC v25.6.0 - help please

I’ve been using ViewPoint3 from within DXO PL 5 (currently v5.16) and previously PL4 and 3, without problems. I wanted to try it as a Photoshop plugin (Photoshop CC v25.6.0). I’ve located and copied the necessary files to the required directory In Windows 10 as per this page:

But no plugins appear and I can’t locate VP3 using the plug-in manager.

Any advice will be appreciated. Thanks.
